If you're asking "Wait; isn't that a bit different from the main photo?", then you're right; this is the standard Paladin; the advanced version is the one displayed in the main photo.

This pic is displaying the suit's primary weapon; the EPLR-194, which is a heavy, automatic plasma weapon with tremendous firepower and ammunition capacity.

This shows you just how big a hardsuit is compared to a standard Iron Federation trooper. No, there is not really an entire minifig in the armor; only the head on top.

This gives you a close-up view of the Paladin's .50 calibur machinegun. The shield on its arm is to protect the weapon's ammunition box and firing mechanisms.

A close-up of the foot. Just soes ya noes.

Now this is the advanced Paladin, used exclusively by Federation hardsuit squad leaders. It's supposed to have a couple of railguns instead of missiles, as well as a flamethrower; but then again, many things are supposed to have stuff.

These are the jump jets, which only elite hardsuit operators are supposed to have. They are not designed for sustained flight; simply really high jumps. Like leaping over tall buildings in a single bound, and all that good fun.

Oh no! The suit's been esploded! No really, this is so no one whines for instructions. I think it's a pretty simple design compared to other hardsuits I've seen here on MOCpages. It's not so poseable, either. But hey, if you've got a massive stash of Bricks, you could probably make an army of these guys.

A close-up of the torso, so you can see how the waist and arms attach. I'd recommend using the upper hole for the arms; and even then it can interfere with swivling the body around.

You WILL make an Iron Federation army of Infantry as well, right? My En Task forces* can mane that thing if your not careful, but I have to be careful about that!!! Its nice anyway.
* A futuristic elite army in my universe, not yet made however
